In-Band Full-Duplex Wireless: Challenges and Opportunities
Ashutosh Sabharwal, Philip Schniter, Dongning Guo +3
In-band full-duplex (IBFD) operation has emerged as an attractive solution for increasing the throughput of wireless communication systems and networks. With IBFD, a wireless termi…
Leveraging Physical Layer Capabilites: Distributed Scheduling in Interference Networks with Local Views
Pedro E. Santacruz, Vaneet Aggarwal, Ashutosh Sabharwal
In most wireless networks, nodes have only limited local information about the state of the network, which includes connectivity and channel state information. With limited local i…
Self-Interference Cancellation with Phase Noise Induced ICI Suppression for Full-Duplex Systems
Elsayed Ahmed, Ahmed M. Eltawil, Ashutosh Sabharwal
One of the main bottlenecks in practical full-duplex systems is the oscillator phase noise, which bounds the possible cancellable self-interference power. In this paper, a digitald…
Self-Interference Cancellation with Nonlinear Distortion Suppression for Full-Duplex Systems
Elsayed Ahmed, Ahmed M. Eltawil, Ashutosh Sabharwal
In full-duplex systems, due to the strong self-interference signal, system nonlinearities become a significant limiting factor that bounds the possible cancellable self-interferenc…
An Upper Bound on the Capacity of Vector Dirty Paper with Unknown Spin and Stretch
David T. H. Kao, Ashutosh Sabharwal
Dirty paper codes are a powerful tool for combating known interference. However, there is a significant difference between knowing the transmitted interference sequence and knowing…
Rate Gain Region and Design Tradeoffs for Full-Duplex Wireless Communications
Elsayed Ahmed, Ahmed Eltawil, Ashutosh Sabharwal
In this paper, we analytically study the regime in which practical full-duplex systems can achieve larger rates than an equivalent half-duplex systems. The key challenge in practic…
